I obviously was talking about "thought-ending" in context of the conversation on what boundaries should be set on speech in which situation. What point are you trying to make? That telling people to shut up means that you want them to shut up? Yes, I think people who want to argue that the holocaust didn't happen or that white people should establish an ethnostate should shut the fuck up. But I wouldn't threaten legal action, no need to bring in a middleman.

Inciting a pogrom.

If speech can cause harm then it is justifiable to redress that harm. If someone wants to argue for free speech absolutism while acknowledging that they are justifying without limit harm and damage to others, by all means they can do so. I think most reasonable people would see how stupid that position is.
